The family again divided into two branches: one, which became extinct about 1780, dwelling at Crevisse, gave several high officials to the Prussian Civil Service; the other branch, which continued at Schoenhausen, generally chose a military career.

August's son, who had the same name as his father, rebuilt the house, which had been entirely destroyed by the Swedes during the Thirty Years' War; he held the position of Landrath, that is, he was the head of the administration of the district in which he lived.

He married a Fraeulein von Katte, of a well-known family whose estates adjoined those of the Bismarcks.

Frau von Bismarck was the aunt of the unfortunate young man who was put to death for helping Frederick the Great in his attempt to escape.

His tomb is still to be seen at Wust, which lies across the river a few miles from Schoenhausen; and at the new house, which arose at Schoenhausen and still stands, the arms of the Kattes are joined to the Bismarck trefoil.
